What will you observe when the leaf A is tested for starch?
A potted plant with variegated leaves was taken in order to prove a factor necessary for photosynthesis. The potted plant was kept in the dark for 24 hours and then placed in bright sunlight for a few hours. Observe the diagrams and answer the questions:
(i) What aspect of photosynthesis is being tested in the above diagram?
(ii) Represent the process of photosynthesis in the form of a balanced equation.
(iii) Why was the plant kept in the dark before beginning the experiment?
(iv) What will be the result of the test performed on leaf ‘A’ shown in the diagram ? Give an example of a plant with variegated leaves.
(v) Draw a neat labelled diagram of a chloroplast.

The diagram given below represents an experiment to prove the importance of a factor in photosynthesis. Answer the following question
What will you observe in the experimental leaf after the starch test?
Two potted plants are destarched by keeping them in dark for 48 hrs and then set up as shown in the below diagrams A and B. The bell jars are made airtight by putting vaseline at the bottom. They are kept in bright sunlight for 8-10 hrs and tested for starch.
Why is KOH kept in jar A?
What would be the result of the final step?
Two potted plants are destarched by keeping them in dark for 48 hrs and then set up as shown in the below diagrams A and B. The bell jars are made airtight by putting vaseline at the bottom. They are kept in bright sunlight for 8-10 hrs and tested for starch.
Why are the plants destarched?
Two potted plants are destarched by keeping them in dark for 48 hrs and then set up as shown in the below diagrams A and B. The bell jars are made airtight by- putting vaseline at the bottom. They' are kept in bright sunlight for 8-10 hrs and tested for starch.
Why is KOH not kept in jar B?
Why is the potassium hydroxide solution as shown in the figure below, kept inside the bell jar?
The figure below represents an experiment performed to demonstrate a particular aspect of photosynthesis. The apparatus was kept in sunlight for almost the whole day. The numeral 1 represents a certain condition inside the flask and numeral 2 represents a chemical responsible for this condition.
What is the object of this experiment?
